My suggestion :

Hurricane > Air Slash for me since Noivern lacks power. Also equip Life Orb because Noivern has very little power without boosting. Noivern without powerful moves and boosting items has damage output almost as low as defensive Pokemon.

Flamethrower a must since Noivern's STABs are helpless against steels.

Tailwind is only useful for teammates most of the time because Noivern already has high speed that can outspeed most of unboosted Pokemon. So make sure your teammates make the best from it :).
